Juventus are reportedly preparing a move for Porto defender Alex Sandro.
The 24-year-old moved to Porto from Santos in 2011 and has since developed into one of the best left-sided defenders in European football.
Porto have already lost Danilo to Real Madrid this summer and had hoped to keep their other Brazilian full-back.
However, according to Gazzetta dello Sport, Juve are confident of acquiring the defender's services before the start of the new campaign.
The same report has claimed that Juve will initially offer £10m.
